Abstract: 目的 了解原发性肾病综合征(PNS)患儿肾功能变化情况,比较肾小球滤过率(GFR)、血浆尿素氮(BUN)和肌酐清除率(Cr)对肾功能的评价作用.方法 使用酶法测定203例PNS患儿和100例健康儿童BUN和Cr,根据Schwartz公式推算GFR,并以此对肾功能进行分期.结果 肾病组BUN和Cr明显高于对照组,而GFR却显著降低;以GFR为分期标准,在203例PNS患儿中,肾功能1期占72.41%,2期占11.33%,3期占9.85%,4期占4.43%,5期占1.97%;GFR、BUN和Cr对PNS患儿肾功能异常的检出率差异有统计学意义,其中GFR最高.结论 PNS患儿存在不同程度的肾功能损害;Schwartz公式推算GFR可以作为临床评价PNS患儿肾功能改变的敏感指标.
